DGC是一个PHP库，用于解码数字绿色证书。简而言之，它解码COVID-19证书。

安装

使用composer进行安装。

$ composer require causal/dgc

用法

$decoder = new \Causal\DGC\Decoder();

// The string as embedded in the QR code of the certificate (e.g., you can use https://qrafter.com/)
$input = 'HC1:NCFOXNYTSFDHJI89.O%26V$L.BUTRDUV...';

// Extract issuer, issuing date, expiring date, type of vaccine, manufacturer, etc.
$data = $decoder->decodeFromQR($input);

{
  1: "DE",
  4: 1643356073,
  6: 1622316073,

      v: [
        {

          co: "DE",
          dn: 2,
          dt: "2021-05-29",
          is: "Robert Koch-Institut",
          ma: "ORG-100031184",
          mp: "EU/1/20/1507",
          sd: 2,
          tg: "840539006",
          vp: "1119349007"
        }
      ],
      dob: "1964-08-12",
      nam: {
        fn: "Mustermann",
        gn: "Erika",
        fnt: "MUSTERMANN",
        gnt: "ERIKA"
      },
      ver: "1.0.0"
    }
  }
}

您可以将数据格式化，使其更易于阅读

// Basically this returns the exact same data you read in the official Swiss app "Covid Cert"
$humanReadableData = $decoder->prettify($data);

{
  issuer: "DE",
  issuingDate: "2021-05-29T21:21:13+02:00",
  expiringDate: "2022-01-28T08:47:53+01:00",
  certificate: {
    type: "vaccination",
